The ALCT4 is an USB base d instrument which can be connected conveniently
to both desktop and laptop computers. The ALCT4’s easy-to-use software allows for the measurement of material parameters for both positive and negative dielectric nematic liquid crystals.
Features
- Elastic Constants Measurements for Both Positive and Negative Dielectric Anisotropic Nematic LC
- Rotational Viscosity of Positive Dielectric Anisotropic Nematic LC
